Tork Teknology P7100 High Performance Overflow Valve 94-98 Dodge 5.9L CumminsDo you experience low fuel pressure at wide open throttle after installing an aftermarket electric lift pump? Unfortunately, this is all too common, but we have the fix. The problem stems from the factory overflow valve having too large of an orifice, which causes excessive fuel to be returned to the fuel tank. The inlet orifice on a standard overflow valve will flow 1. 14 GPM back to the tank. If you are running a 100 GPH pump, you are pumping 1. 66
Do you experience low fuel pressure at wide open throttle after installing an aftermarket electric lift pump? Unfortunately, this is all too common, but we have the fix. The problem stems from the factory overflow valve having too large of an orifice, which causes excessive fuel to be returned to the fuel tank. The inlet orifice on a standard overflow valve will flow 1.14 GPM back to the tank. If you are running a 100 GPH pump, you are pumping 1.66 GPM, which means you are losing 69% of your pump volume through the stock overflow valve. Seeing these numbers makes it fairly obvious why there is a significant power loss at higher RPM.
We offer this simple and effective overflow valve in four different sizes, so which one is right for you?
The general rule to determine the fuel pressure you should be at is to multiply the governor spring RPM (in thousands) by 10. In other words, you want 10 PSI of fuel pressure per 1000 RPM of governor speed. So, if you installed a 3K governor spring kit, you need a minimum of 30 PSI at full power, a 4K kit requires 40 PSI at WOT, and 5K equates to 50 PSI at WOT.
- The OFV040HP has the largest orifice for street use. This valve is for lightly modified street performance trucks in the 275 to 350 horsepower range running an AirDog or FASS pump. Fuel pressure will range between 30 to 37 PSI.
- The OFV050HP has the second largest orifice for street use. This valve is for moderately modified street performance trucks in the 350 to 450 horsepower range using an AirDog or FASS pump. Fuel pressure is in the 37 to 45 PSI range, at full power.
- The OFV060HP has the third smallest orifice for highly modified Cummins diesel engines. This valve is for heavily modified street performance trucks in the 500 to 600 horsepower range using an AirDog or FASS pump. Fuel pressure will be in the 43 to 50 PSI range, at full power.
- The OFV075HP has the smallest orifice, and is NOT for street use, because it will not provide adequate long term cooling to the pump.
IMPORTANT NOTE: Do not use the HP valve on a stock fuel system! The valve is intended for P pump trucks using a FASS, Air Dog or high volume, performance fuel pump only.

🦴 Micro Bone, Major Relief; Perfect Puppy Teething Chew Toy
Size: X-Small, Color: Blue, Size: X-Small, Color: Blue
🐾 Hi, I’m PVD; teething survivor, nub enthusiast, and gum massage advocate.
This tiny blue bone was my day-one favorite from 8 weeks to 5.5 months, it handled every chew session, tantrum, and tooth eruption with dignity. I’ve officially “aged out,” but I still salute it.
⭐ Why it earned 5 stars:
✔️ Perfect XS size for toy breed jaws
✔️ Soft on sore gums, durable enough for dramatic chewing
✔️ Ridges + nubs = mouth spa treatment
✔️ Chilling it = elite teething relief
✔️ Kept me busy and prevented chewing on illegal things (furniture, shoes… mother)
🌀 Why I’m now gracefully retiring it (but still recommending):
✘ Jaw strength and confidence grew but I didn’t vibe with the larger size versions (tried and rejected them with judgment)
✘ Texture now too gentle for my post-teething chew style
✘ Advanced chewers may get bored once the rage-chewing era passes
✘ I get gum relief via Nylabone Nubz edible chews now
Best For:
• XS-Small breed puppies, especially under 5 lbs
• Teething stages + gum relief
• Delicate chewers or fur babies still in the love-bite phase
• First-time puppy parents (trust me, this bone prevents household drama!)
• 8 weeks–6 months old
🚫 Not for adult teeth or advanced chew techniques.
📝 Final Re-Barks:
Iconic starter bone for toy breed pups. Affordable, safe, and genuinely soothing during teething chaos. It carried me through the hardest months (and saved several legs; both human and furniture). I’ve outgrown it; but I’ll forever endorse it for the next generation of tiny chewers.

Nylabone Puppy Treat Starter Pack - A Mixed Bag of Delight and Disappointment
Size: Small, Color: Blue
I recently purchased the Nylabone Puppy Treat Starter Pack for my adorable 5lb puppy, and overall, I have mixed feelings about this product. While I was initially satisfied with the variety pack, one of the bones in particular left me disappointed due to its lack of durability.
Let's start with the positives. The Nylabone Puppy Treat Starter Pack comes with three different toys: a blue puppy teething toy, a nylon dog toy, and a chew treat. This variety is great for keeping my puppy engaged and entertained, especially during the teething phase. The blue puppy teething toy is specifically designed for soothing sore gums, and my puppy seemed to find great relief when chewing on it. It has a pleasant texture that is gentle on the teeth and gums, making it an ideal choice for teething puppies.
The nylon dog toy included in the pack is durable and sturdy. It has a satisfyingly textured surface that provides an excellent chewing experience for my little furry friend. The toy is designed to withstand the strong chewing habits of puppies, and it has certainly proven to be long-lasting compared to other toys I've tried in the past. My puppy enjoys gnawing on it for extended periods without any signs of damage.
Now, let's address the bone that failed to meet expectations. One of the bones included in the pack was devoured by my puppy within a single evening. I was taken aback by how quickly it was consumed, especially considering my puppy's small size. While the other bones in the pack held up well, this particular one lacked the durability I had hoped for. I understand that puppies have strong jaws, but I expected the bone to withstand more than a few hours of chewing.
Despite this disappointment, I must mention that the bone did not cause any harm to my puppy. It is important to supervise your puppy while they chew on any toys, especially if they have a tendency to swallow large chunks. In this case, I was fortunate that my puppy did not experience any adverse effects after consuming the bone. However, it's crucial to exercise caution and ensure that your puppy doesn't ingest anything that could potentially be harmful.
Overall, while the Nylabone Puppy Treat Starter Pack has its upsides, I cannot ignore the fact that one of the bones failed to meet expectations in terms of durability. However, the other toys included in the pack provided a satisfactory experience for my puppy, and they have proven to be long-lasting. I would recommend this product with the caveat that you closely monitor your puppy's chewing habits and potentially avoid the bone that didn't hold up well in my particular case.

⭐⭐⭐⭐⭐ Great for teething puppies
Size: Small, Color: Pink
I purchased the Nylabone puppy chew toys for my teething puppy, and they’ve been a big help. The toys are the perfect size for a young puppy and feel durable without being too hard.
My puppy enjoys chewing on them, and they’ve helped redirect chewing away from furniture and shoes. I also like that they’re designed specifically for puppies, so they’re gentle enough for growing teeth and gums.
The variety in the set keeps my puppy interested, and the toys have held up well with daily use. They’re easy to clean and feel safe to give to a puppy.
Overall, these are great chew toys for puppies. They’re effective, well made, and helpful during the teething stage. I would definitely recommend them to new puppy owners.

Size: X-Small, Color: Pink
Our new puppy loves the texture and thickness of this bone. She is an aggressive chewed and has not yet destroyed this bone. We have purchased Nylabones for our dogs year after year and have had several happy puppies over the years.

Great Variety for Teething Puppies, Keeps Him Busy!
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
I got this 9-pack toy set for my 11 lb chihuahua-terrier mix puppy, and it’s been very well received by my little guy. He’s been bored being in quarantine until his vaccines kick in and he's also teething. This toy set has made a huge difference.
Great variety - you get a combination of rope toys, plush squeaky toys, and even a treat ball, so he often rotates between them depending on what he wants. The rope toys have been especially good for teething, while the softer toys keep him entertained. One of the plush toys has that crinkly texture inside, which he loves.
The treat ball is a nice bonus too. I've put treats and his dog kibble in there throughout the day, and it helps keep him engaged and also mentally tires him out.
Everything is sized well for a small puppy and light enough for him to carry around easily.
The materials feel decent for the price, especially considering how many toys you get. That said, I do keep an eye on him with the softer ones since he’s still a puppy and likes to chew.
Pros:
Good mix of rope, plush, and interactive toys
Great for teething and keeping him occupied
Treat ball adds a mental challenge
Good size for small dogs/puppies
Nice value for the number of toys
Cons:
Softer toys may wear down faster with heavier chewing
Overall, this has been a really useful set during a phase where he’s both teething and needs a lot of mental stimulation. I’d recommend it for small dogs or puppies, especially if you want a variety instead of buying individual toys.
